Okay, bought a dinghy with a 2008 Suzuki 25 4-stroke electric-start on it from an estate sale. It starts just fine, but won't run below the start notch on the tiller (no idle). The primer bulb doesn't stay hard (no wisecracks; wife already made them, thank you very much). Don't have a manual, and of course Suzuki doesn't have any online info. The plugs are clean and the gas smells OK. I dumped the separator bottle on the engine,didn't see gunk or water. Do I have a plugged low-speed jet? It's like a switch; there is NO life below the start notch. I also know the engine was running just fine recently. Any rays of sunshine?

Just what does " the gas smells OK" mean have you drained tank and filled with fresh fuel?

More than likely the pilot/ idle passages need cleaning

I'll dump the tank and try it.

"the gas smells OK" means it doesn't smell dead; it's fresh. Nevertheless, I dumped it for a new tank. Turns out the right-hand cylinder isn't firing.

Check compression and then spark with a spark tester.
If all is good with that then clean the carbs
